1. A process of extracting higher plants or fungi polysaccharides based on a microwave chemistry treatment, comprising the following steps:

  • a treating pulverized higher plants or fungi with an organic solvent to remove liposoluble components thereof, to obtain higher plants or fungi residue;

    or directly using pulverized higher plants or fungi;

    b) putting the residue or pulverized higher plants or fungi obtained in the step a) into a microwave reaction chamber, adding an acid solution of a mass concentration of 5% to 99%, conducting reaction of the mixer for 5-120 mins at a microwave power of mass power density of 1 kilowatt per kilogram of material-10 kilowatts per kilogram of material under a work pressure of 20 mmHg-760 mmHg;

    optionally conducting concentration, and then washing with an organic solvent to remove excess acid; and

    c) conducting extraction by adding water solution of 5-15 times by volume into the product obtained from the step b), subjecting the extraction solution after concentration to alcohol precipitation, separating precipitates, i.e. the polysaccharides.
